Reading the season in Detroit Dam
With roughly 269 frost-free days, Detroit Dam gardens fit long-season crops — melons, winter squash, sweet potatoes — with room left for spring and fall rounds of greens and roots. The first frost around Dec 3 is late enough that fall planting is a full second season, not an afterthought.
